AM62P: Suspend-to-RAM Without Timer and Wake Using WKUP R5

Part Number: AM62P

Hi,

I am using AM62Px with Android on the A53 cores and FreeRTOS on the WKUP R5.

In the Android Low Power documentation (https://software-dl.ti.com/processor-sdk-android/esd/AM62PX/10_00_00/docs/devices/AM62PX/android/Application_Notes_Android_Low_Power.html), I found that Suspend-to-RAM can be entered using:

rtcwake -s <time> -m mem

This wakes the system automatically after the specified time.

Our requirement is to put the system into Suspend-to-RAM without a timer and wake it only when the WKUP R5 detects a wake-up event (CAN wake/GPIO).

Is this supported? If yes, what is the recommended way to enter Suspend-to-RAM without using rtcwake, and what configuration is required to allow the WKUP R5 to wake the system?

Thanks.
